Noise

[darrsi]

I may be being naive here but you've said repeatedly that the noise goes away when you pull the clutch lever? So surely the first thing to do would be check over the clutch?
I've no clue what it could be but just seems logical no?

I have considered it maybe clutch slip, but i know what that feels like and the bike is showing no signs of that whatsoever, i can give the throttle a lot of welly without any slipping feeling at all, plus i remember that is more of a higher pitched grinding sound.
